The document discusses BiPAP machines which are used to treat sleep apnea. BiPAP stands for Bilevel Positive Airway Pressure and uses two pressure settings, inhale and exhale pressure, unlike CPAP which uses a single pressure setting. A BiPAP machine includes a main unit to pressurize air, a humidifier, tube, and mask. The mask delivers pressurized air to help patients breathe steadily and get better sleep. Benefits of BiPAP treatment include better sleep quality, reduced snoring, decreased daytime fatigue, improved focus and moods, and lower blood pressure and health risks.
